CANVAS: Canagliflozin improved renal outcomes in diabetes

Article Type
Changed
Tue, 05/03/2022 - 15:19

AUSTIN, TEX. – Canagliflozin can improve renal outcomes in patients with type 2 diabetes, even when they have mild or moderate kidney disease, new data from the CANVAS program suggested.

“The effect of canagliflozin on composite renal outcomes was large, particularly in people with preserved kidney function,” Brendon L. Neuen, MBBS, of University of New South Wales, Sydney, and his associates wrote in a poster. Baseline renal function also did not appear to affect the safety of canagliflozin, the investigators reported at a meeting sponsored by the National Kidney Foundation.

In patients with diabetes mellitus, increased proximal reabsorption of glucose and sodium decreases the amount of sodium reaching the macula densa in the distal convoluted tubule. This results in reduced use of adenosine triphosphate for sodium reabsorption, which thereby decreases adenosine release and vasoconstriction of afferent arterioles. Left unchecked, this dampening of the tubuloglomerular feedback mechanism increases glomerular filtration and leads to diabetic nephropathy.

Sodium glucose cotransporter 2 (SGLT2) inhibitors such as canagliflozin (Invokana) and empagliflozin (Jardiance) help mitigate this pathology by vasoconstricting afferent arterioles. Previously, in an exploratory analysis of the multicenter, placebo-controlled EMPA-REG OUTCOME (Empagliflozin, Cardiovascular Outcomes, and Mortality in Type 2 Diabetes) trial, empagliflozin led to modest but statistically significant long-term reductions in urinary albumin secretion for diabetic patients, regardless of their baseline urinary albumin to creatinine ratio (Lancet Diabetes Endocrinol. 2017 Aug;5[8]:610-21). Treatment with empagliflozin also significantly reduced the risk of developing microalbuminuria or macroalbuminuria (P less than .0001).

The multicenter, double-blind, placebo-controlled CANVAS (Canagliflozin Cardiovascular Assessment Study) and CANVAS-R (A Study of the Effects of Canagliflozin on Renal Endpoints in Adult Participants with Type 2 Diabetes Mellitus) trials included more than 10,000 adults with type 2 diabetes and high cardiovascular risk. In the primary analysis, canagliflozin significantly reduced the risk of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke compared with placebo (N Engl J Med. 2017 Aug 17;377[7]:644-57).

Dr. Neuen and his associates compared the effects of canagliflozin on renal outcomes and safety among CANVAS patients whose estimated glomerular filtration rate (eGFR) was preserved (greater than 60 mL/min per 1.73 m2) or reduced (less than 60 ml/min per 1.73 m2). Actual mean eGFRs in each of these groups were 83 mL/min per 1.73 m2 and 49 mL/min per 1.73 m2, respectively. Compared with placebo, canagliflozin acutely reduced eGFR in patients with either preserved (average, –2.2 mL/min per 1.73 m2) or reduced (–2.83 mL/min/1.73 m2 ) baseline kidney function (P = 0.21).

 

 

Among patients with preserved function at baseline, canagliflozin was associated with a statistically significant 47% decrease in risk of renal death, end-stage kidney disease, or a 40% or greater drop in eGFR (hazard ratio, 0.53; 95% confidence interval, 0.39-0.73). Canagliflozin also showed renal benefits for patients with reduced kidney function, but the effect did not reach statistical significance (HR, 0.76; 95% CI, 0.49-1.17). Findings were similar when the researchers tweaked the composite renal endpoint by replacing the eGFR criterion with doubling of serum creatinine (HR, 0.42; 95% CI, 0.23-0.75 and HR, 0.81; 95% CI, 0.37-1.77, respectively).

Canagliflozin has a black box warning for amputation risk. There was no indication that early renal function further increased this risk, the researchers reported. CANVAS patients who received canagliflozin underwent amputations (usually at the level of the toe or metatarsal) at rates of 6.3 per 1,000 person-years overall, 5.6 per 1,000 person-years in the setting of preserved kidney function, and 9.9 per 1,000 person-years in the setting of reduced kidney function. Rates in the placebo group were 3.4, 3.0, and 4.8 amputations per 1,000 person-years, respectively. Additionally, baseline renal status did not significantly affect risk of fracture, serious kidney-related adverse events, or serious acute kidney injury. Patients with baseline renal insufficiency were at increased risk of developing serious hyperkalemia (HR, 2.11; P = .06), but these events were uncommon in both treatment groups.

No CANVAS patient had stage 4 or worse kidney disease (eGFR less than 30 mL/min per 1.73 m2) at enrollment, the researchers noted. The ongoing phase 3 CREDENCE (Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation) trial will shed more light on canagliflozin in the setting of renal disease, they added. This multicenter, double-blind trial compares canagliflozin with placebo in more than 4,000 patients with diabetic nephropathy. Results are expected in 2019.

Janssen funded the CANVAS and CANVAS-R trials. Disclosures were not provided.

This multicenter, double-blind trial compares canagliflozin with placebo in more than 4,000 patients with diabetic nephropathy. Results are expected in 2019.

Janssen funded the CANVAS and CANVAS-R trials. Disclosures were not provided.

– A company that partners patients and health advisers claims to help patients with type 2 diabetes to manage their symptoms and lower their HbA1c levels.

The Pack Health program connects each patient with a health adviser, who contacts them five times a week using a mix of phone calls, text messages, and emails. The goals include helping patients to find clinicians in their area, make appointments, and adhere to treatment, Dhiren Patel, PharmD, medical director at Pack Health, said at the annual meeting of the American Association of Clinical Endocrinologists.

In a prospective study of 756 type 2 diabetes patients, traditional modes of communication with a health coach were associated with a 1% decrease in HbA1c within 3 months and the reduction was maintained at 1 year. Patients lost an average of 5 pounds, and annual eye and foot exams increased by 17% and 19%, respectively.

Similar remote health coach initiatives are being used to help other patients with chronic health conditions as part of the Pack Health services, which Dr. Patel discussed in a video interview.

For Gram-negative bacteremias, 7 days of antibiotics is enough

Article Type
Changed
Fri, 01/18/2019 - 17:40

– Seven days of antibiotic therapy was just as effective as 14 days for patients with Gram-negative bacteremias.

The shorter course was associated with similar cure rates and a faster return to normal activities, Dafna Yahav, MD, said at the European Society of Clinical Microbiology and Infectious Diseases annual congress.

Dr. Dafna Yahav

“In patients hospitalized with Gram-negative bacteremia and sepsis, a course of 7 antibiotic days was not inferior to 14 days, and resulted in a more rapid return to baseline activity, “ said Dr. Yahav of the Rabin Medical Center, Petah Tikva, Israel. “This could lead to a change in accepted management algorithms and shortened antibiotic therapy. Potentially, though we did not show this in our trial, it may lead to reduced cost, reduced development of resistance, and fewer adverse events.”

During the past few years, a new dogma has emerged in antibiotic treatment paradigms, she said: Shorter is better. Brad Spellberg, MD, described this concept in his 2016 editorial in JAMA Internal Medicine, “The new antibiotic mantra” (Sep 1;176[9]:1254-5).

In it, Dr. Spellberg, of the University of Southern California, Los Angeles, addressed the long-held view that a full 10- or 14-day course of antibiotics was necessary to decrease the risk of creating a resistant strain, even if clinical symptoms were long resolved.

However, he noted, there is little evidence supporting the idea that longer courses suppress the rise of resistance – and, in fact, some data support the opposite.

“To the contrary, specifically for pneumonia, studies have shown that longer courses of therapy result in more emergence of antibiotic resistance, which is consistent with everything we know about natural selection, the driver of antibiotic resistance,” he noted. “In only a few types of infections does resistance emerge at the site of infection; rather, resistance typically emerges off target, among colonizing flora away from the site of infection. Thus, all that is achieved by treating an infection with antibiotics for longer than the patient has symptoms is increased selective pressure driving antibiotic resistance among our colonizing microbial flora.”

 

 

The European Union and Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America have all recently updated their antibiotic stewardship guidelines to include a strong recommendation for the shortest effective duration of antimicrobial therapy.

However, most of the supporting data were drawn from randomized, controlled studies of patients with lung, skin, and kidney infections. Short-course treatments have not been adequately studied in bacteremia patients, Dr. Yahav said.

The aim of her study, which was investigator initiated and received no external funding, was to demonstrate the noninferiority of 7 days of antibiotic therapy, compared with 14 days, in patients with bacteremia arising from Gram-negative infections.

The randomized, open-label study comprised 604 patients in three hospitals: two in Israel and one in Italy. Patients were eligible if they had an aerobic Gram-negative bacteremia of any infection source that was either community- or hospital acquired. The medication choice was left up to the treating physician. Patients were assessed at discharge, and at days 30 and 90.
 

 

The primary outcome was a composite 90-day endpoint of all-cause mortality, clinical failure (relapse, new local complications, or distant complications), and readmission or hospital stay longer than 14 days. There were a number of secondary outcomes, including new infection, emergence of antibiotic resistance, total hospital and total antibiotic days, time to return to baseline activity, and adverse events.

The cohort was a mean of 71 years old. About 60% were functionally independent, and the mean Charlson comorbidity score was 2. Most of the infections (90%) were nosocomial. The urinary tract was the largest source of infection (69%). Other sources were abdominal, respiratory, central venous catheter, and skin or soft tissue.

Escherichia coli was the most common infective organism (62%), followed by Klebsiella species and Enterobacteriaceae. A small number of patients had Acinetobacter and Pseudomonas infections.

In the intent-to-treat analysis, the primary composite outcome of all-cause mortality or extended hospital stay occurred in 46% of the 7-day group and 50% of the 14-day group – not significantly different. The results were nearly identical in the per-protocol analysis (46% vs. 49.6%).

 

 

Likewise, none of the secondary outcomes posted a significant difference in favor of one treatment arm, including relapse (2.9% vs. 2.7%) and resistance development (10.8% vs. 9.7%).

Dr. Yahav pointed out that total antibiotic-use days were significantly less in the 7-day group, (5 days) than in the 14-day group (10 days). Patients in the short-duration group returned to their normal activities a day earlier than those in the longer-term group (2 days vs. 3 days), a difference that was statistically significant.

The total hospital stay from randomization to day 90 was only half a day shorter in the short-term group (mean, 3 days vs. 3.5 days). That was not a significant finding.

There were some differences in adverse events, although none was statistically significant. The short-duration arm had slightly more cases of kidney injury (0.5%), fewer cases of liver function abnormalities (–1.5%), and half as many rashes (two vs. four). There were two cases of Clostridium difficile in the short-use arm and one in the long-use arm, also not a significant difference.
 

 


A subgroup analysis looked at outcomes among the different sources of infection (urinary tract vs. other), whether empirical antibiotics were used, and whether the induced resistance was multdrug or non–multidrug. All of those differences hovered close to the null, but generally favored short antibiotic treatment, Dr. Yahav noted.

“I would conclude from these data that is generally safe to stop antibiotics after 7 days of covering antibiotics for Gram-negative bacteremia patients, if they are hemodynamically stable and nonneutropenic at 7 days, and have no uncontrolled source of infection,” she concluded.

The investigator-initiated study had no outside funding.

Blood type A linked to more-severe diarrhea

Article Type
Changed
Wed, 05/26/2021 - 13:49

Diarrhea associated with enterotoxigenic Escherichia coli (ETEC) infection is more severe among individuals with blood type A, based on data from 106 adults exposed to the agent.

The reseachers speculate that the increased severity is related, in part, to the presence of an adhesin molecule known as EtpA, which binds to the surface of the cells and combines with blood group A glycans to promote a more severe infection.

“Our studies suggest that the many ETEC strains that produce the EtpA adhesin may be particularly well equipped to preferentially infect hosts who express A blood group antigen on mucosal surfaces,” wrote Pardeep Kumar, MD, of Washington University, Saint Louis, and his colleagues.

ETEC, associated with choleralike illness, remains a major cause of infectious diarrhea in developing countries. No current vaccine offers significant protection against it, but EtpA may be useful in vaccine development. “More recently discovered virulence factors and an improved understanding of ETEC microbial pathogenesis could offer additional avenues to protect those at highest risk for severe disease and uncover novel molecular targets for future vaccine development,” the researchers said.

In a study published in the Journal of Clinical Investigation, the researchers examined blood samples from 106 adults who had participated in previous human infection model studies. The volunteers were challenged with an ETEC strain known as H10407 that was originally isolated from a case of choleralike illness.

Diarrhea was more frequent among A blood type individuals, compared with other types. Individuals with B or O blood types were significantly more likely to have no diarrhea or mild diarrhea after the E. coli challenge, compared with type A individuals (44% vs. 19%).

Overall, significantly more individuals with A or AB blood types developed moderate to severe diarrhea, compared with those with B or O blood types (81% vs. 56%). In addition, significantly more individuals with blood type A needed early initiation of antibiotic therapy, compared with those with B or O blood types (72% vs. 43%).

 

 

The study findings were limited by several factors, including the use of higher levels of bacteria to cause the infection than a typical exposure in nature. Also, the volunteers were treated with antibiotics once they met the criteria for severe diarrhea.

The researchers also noted that other blood group A lectins in addition to EtpA may not have been identified.

“While our recent studies have potentially important clinical and [vaccinological] implications, further study of the relationship between blood group, disease severity, and antigen expression could guide and inform use of these antigens in vaccines,” they wrote.

The study was supported by funds from the Enteric Vaccine Initiative of PATH, the Department of Veterans Affairs, the National Institutes of Health, and the Digestive Diseases Research Core Center at Washington University School of Medicine, St. Louis. The researchers had no financial conflicts to disclose.

Canagliflozin linked to lower HbA1c levels in younger patients

– The effects of canagliflozin on hemoglobin A1c levels were greater in participants under age 65 years in randomized clinical trials of the SGLT2 inhibitor, according to results of a prespecified subgroup analysis.

Some cardiovascular, renal, and mortality outcomes also varied by age group, according to the analysis of participants in the CANVAS (Canagliflozin Cardiovascular Assessment Study) program. Despite those differences, the effect of canagliflozin was generally consistent on other outcomes, such as body weight and blood pressure, in patient grouped into those aged less than 65 years and those aged 65 years and older, investigators reported at the annual meeting of the American Association of Clinical Endocrinologists.

Nonfatal MI, nonfatal stroke, and the composite of doubling of serum creatine, end-stage renal disease, or renal death were lower in study participants aged 65 and older on canagliflozin. Lower risks of cardiovascular death and all-cause mortality were seen in participants under age 65 years who were taking canagliflozin. However, “these results should be interpreted with caution given the large number of subgroup analyses performed,” wrote Fernando Ovalle, MD, director of the multidisciplinary comprehensive diabetes clinic at the University of Alabama at Birmingham, and his colleagues.

Canagliflozin was found to reduce risk of the composite endpoint of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke versus placebo in previously published results of the CANVAS study, which included individuals with type 2 diabetes mellitus who either had or were at high risk for having cardiovascular disease.

The two multicenter, randomized, controlled trials, CANVAS and CANVAS-R, included more than 10,000 patients. The subgroup analysis presented here at the AACE meeting included 5,578 patients aged less than 65 years (55%) and 4,564 patients aged 65 years or older (45%).

The subgroup analysis found that placebo-subtracted differences in HbA1c were greater in patients under 65 years than those in patients 65 or older (–0.7% and –0.5%, respectively; P less than .0001). However, there were no significant differences by age group in body weight changes, systolic blood pressure, or diastolic blood pressure.

 

 

Patients aged 65 years or older at baseline had a lower risk of nonfatal MI and nonfatal stroke with canagliflozin versus placebo (P for heterogeneity, .02 and.01, respectively), according to investigators. Older patients also had lower risk of the composite of serum creatinine doubling, end-stage kidney disease, or renal death with canagliflozin versus placebo (P = .01).

Patients aged less than 65 years at baseline had lower risk of cardiovascular death (P = .01) and all cause mortality (P = .01) for canagliflozin versus placebo.

Dr. Ovalle reported disclosures related to Merck, AstraZeneca, Sanofi Pasteur, Novo Nordisk, GlaxoSmithKline, Janssen, Eli Lilly, Medtronic, Pfizer, and GI Dynamics, along with the National Institutes of Health and Juvenile Diabetes Research Foundation.

Most COPD patients on triple therapy can withdraw steroids

Article Type

Fri, 01/18/2019 - 17:40

– In patients on long-term triple therapy and up to one exacerbation in the previous year, the withdrawal of inhaled corticosteroids (ICS) led to a small decrease in lung function that was not clinically important, with no associated difference in the rates of chronic obstructive pulmonary disease (COPD) exacerbations, dyspnea or as-needed bronchodilator use.

Those are key findings from the SUNSET trial, a 26-week, randomized, double-blind, parallel-group multicenter study to assess the efficacy and safety of the switch from long-term triple therapy to indacaterol/glycopyrronium (IND/GLY, 110/50 mcg once daily) or continuation of triple therapy with tiotropium 18 mcg once daily and salmeterol/fluticasone propionate fixed-dose combination 50/500 mcg b.i.d.

Dr. Kenneth R. Chapman
When patients with COPD are receiving triple therapy but are not having frequent exacerbations, it’s safe to ‘de-escalate’ to the bronchodilator foundation of second generation LABA/LAMA,” lead study author Kenneth R. Chapman, MD, said in an interview prior to an international conference of the American Thoracic Society. “In a minority of patients with high blood eosinophil counts, one should make the move cautiously.”

Dr. Chapman, director of the asthma and airways clinic at University Health Network, Toronto, noted that relatively few patients with COPD benefit from inhaled steroids. “Given the risk of adverse events (pneumonia, osteoporosis, etc.), we’d rather not give them when they’re not needed,” he said. “Inhaled steroids seem to play only one role in COPD: They tend to reduce exacerbations in the exacerbation-prone COPD patient. That’s about 20% of the COPD population. Despite this, a great many patients end up on triple therapy [long-acting bronchodilators/long-acting muscarinic antagonist (LABA/LAMA) and ICS] needlessly.”

For the study, Dr. Chapman and his associates enrolled 1,053 patients with moderate to severe COPD who’d had no more than one exacerbation in the previous year who had used triple therapy for at least 6 months prior to study inclusion. The primary endpoint of the study was noninferiority on change from baseline in postdose trough forced expiratory volume in 1 second (FEV1) (with a noninferiority margin of –50 mL) after 26 weeks. Exacerbations, health-related quality of life as measured by the St. George’s Respiratory Questionnaire (SGRQ-C), and breathlessness as measures by the Transition Dyspnea Index also were evaluated. Of the 1,053 patients, 527 were randomized to IND/GLY and 526 to triple therapy. Their mean age was 65 years and their mean postbronchodilator FEV1 was 1.6 L.

The researchers found that ICS withdrawal led to a mean reduction in trough FEV1 of –26 mL, which exceeded the noninferiority margin. This difference between treatments on trough FEV1 was driven by the subset of patients with high blood eosinophil counts at baseline (a mean of –68 mL for patients with at least 300 cells/mcL and a mean of –13 mL for patients with fewer than 300 cells/mcL). The two treatments showed similar annualized rates of moderate/severe COPD exacerbations (rate ratio, 1.08) and all (mild/moderate/severe) exacerbations (RR, 1.07). ICS withdrawal led to a small difference in SGRQ-C (1.4 U on week 26), but no differences in Transition Dyspnea Index or use of rescue medication over 26 weeks. Safety and tolerability were balanced across the two treatment groups.

“Although we found no overall increase in exacerbations with ‘de-escalation,’ there were, of course, exacerbations that occurred during the trial,” Dr. Chapman said. “We found that they tended to occur in the minority of patients who had elevated blood eosinophil counts, especially if the counts were elevated persistently (at screening and randomization). The relevant cut-point was blood eosinophil counts above 300/UL. If exacerbations did occur in this easily identifiable subpopulation, they tended to occur early, in the first month after de-escalation. This gives physicians a simply way to identify a population they might exercise caution and a period when careful monitoring is useful.”

 

 


He acknowledged certain limitations of the study, including its 6-month duration, which is shorter than most exacerbation studies. “But by recruiting at multiple sites in multiple countries and across seasons, we don’t think this was an importation limitation,” he said. “Of course, like most investigators, I can always think of things I wish I had tracked. My personal hunch is that FeNO [exhaled nitric oxide levels] might offer some useful information but that will be a hunch to explore in another study.”

SUNSET was sponsored by Novartis. Dr. Chapman disclosed that he has received fees for research, consulting and lectures from Novartis, as well as from several other pharmaceutical companies.
